CONTAINER Filed Oct. 50, 1952 INVENTOR- WILLIAM T. STEARN BY ATTORNEYS.

1 2,760,631 CONTAINER William '1. Steam, Caii, Colombia, assignor to Celanese Colombiana, S. A., Cali, (Colombia, a corporation of Colombia Application October 30, 1952, Serial No. 317,767 1 (Ilaim. (Cl. 2116-65) This invention relates to containers, and relates more particularly to containers for storing and shipping packages of yarn.

The bulk of the yarn produced in the textile industry is wound into packages, such as bobbins, cones, cheeses, pirns and the like. During the storing and shipping of these yarn packages they must be supported so as to prevent them from rubbing against each other or against the walls of the carton or other container in which they arestored or shipped, since such rubbing would mar at least the outer layers of yarn on said packages. The cartons heretofore employed for storing and shipping yarn packages have included means, such as apertured inserts, for engaging the yarn packages so as to prevent move ment thereof and damage to the yarn wound thereon. However, these cartons have been relatively expensive and have required a considerable amount of labor for their assembly and disassembly, thereby increasing the handling costs in storing and shipping the yarn packages. In addition, these cartons have failed to provide adequate support for the yarn packages, with the result that yarn damage frequently occurred, particularly when the loaded cartons were subjected to shocks during handling or shipping.

It is an important object of this invention to provide a carton for storing and shipping packages of yarn which will be free from the foregoing and other disadvantages of the cartons hitherto employed for this purpose, and which will be especially simple in construction and efficlent in use.

A further object of this invention is the provision of a carton for storing and shipping packages of yarn which will engage and support said packages in separated condition so as to avoid relative displacement thereof and damage to the yarn wound thereon.

Other objects of this invention, together with certain details of construction and combinations of parts, will appear from the following detailed description and the accompanying drawing.

In the drawing wherein a preferred form of my invention is shown the figure is a sectional perspective view of the container of my invention, with certain elements omitted in the interest of clarity.

Like reference numerals indicated like parts throughout the drawing.

Referring now to the drawing, reference numeral 11 designates generally a package of yarn which comprises a central tube 12 on which the yarn is wound in a manner providing a cylindrical portion 13 about the middle of the tube 12 and a conical tapered portion 14 at each end of the cylindrical portion 13. The yarn packages 11 are carried in several layers in a corrugated paper box designated generally by reference numeral 16, which comprises a bottom 17, side walls 18 and a cover (not shown). For sake of clarity, only one yarn package 11 in each layer is illustrated in the drawing. To hold the packages 11 securely in the box 16 there are provided a plurality of

corrugated paper pads

19, 21 and 22, which are held against sidewise movement by engagement with the walls 18 of the box 16. Bottom pads 19 have a plurality of circular holes 23 into which each tube 12 fits snugly. Intermediate pads 21 are provided with integral triangular resilient flaps 24, which tightly engage the upper tapered portions 14 of the yarn package 11. Each top pad 22 rests on the tops rates Parent of the tubes 12 of a layer of yarn packages and provides support for the bottom pads 19 of the next layer of yarn packages. If desired, top pads 22 may be secured to the bottom pads 19 which rest thereon, as by adhesives or stapling (not shown).

The triangular resilient flaps 24 are formed by cutting intermediate pad 21 along groups of lines 26, preferably of equal lengths, radiating from centers 27, so that each triangular flap 24 of each group, as cut, points toward the center 27 of that group, with the centers 27 being vertically aligned with the centers of the holes 23 in bottom pads 19. When bent upwardly out of the plane of pad 21, each group of flaps 24 defines an opening surrounded by said triangular flaps for engaging a tapered portion 14 of a yarn package 11. If desired the tops of intermediate pads 21 may be scored around the base of each triangular flap 24, as shown by reference numeral 28, to make it easier to bend these flaps upwardly. It is preferred that the flaps 24 be of equal size and shape.

The resilient triangular flaps 24 fit about the yarn packages in such a manner that only the smooth outer surface of the corrugated paper comes into contact with the yarn, which is not touched by any raw edge of corrugated paper. In addition, the intermediate pads 21 are self-adjusting. If the openings in the intermediate pad 21 around the tapered portions 14 of the yarn package become larger during use, the pad 21 will position itself anew so that it fits the tapered portions 14 at all times.

While, for simplicity, only two layers of yarn packages are shown in the drawing, any desired number of layers may be employed.

It is to be understood that the foregoing detailed description is given merely by way of illustration and that many variations may be made therein without departing from the spirit of my invention.

Having described my invention, what I desire to secure by Letters Patent is:

A device for the storing and shipping of packages of yarn, comprising a container, packages of yarn arranged in superposed layers in said container, each of said pack ages of yarn having two cylindrical ends and two tapered surfaces joining a medial cylindrical portion of larger diameter than that of the cylindrical ends, a bottom flat pad, for each layer, having apertures engaging one of said cylindrical ends, a top flat imperforate pad abutting the opposite ends of said yarn packages and underlying and supporting the apertured pad for the layer above, and an intermediate flat pad of corrguated paper, said intermediate pad being closer to said top pad than to said bottom padand having separate groups of triangular flaps integral at their bases with said pad and pointing toward a common center, each group of flaps, bent out of the plane of said intermediate pad, defining an opening in said pad surrounded by said flaps and engaging one of the tapered surfaces of each yarn package, said groups of flaps preventing relative movement of the packages, said intermediate pads being supported by said packages whereby they are self-adjusting during use.
